Virtual level app for iPad, iPhone

This free app has been redesigned to be compatible with iPhone 5 features like Retina display. It harnesses the technology of an accelerometer and a digital gyroscope located in select iPhone and iPad models, to generate an understanding of where the device is in space. After initial calibration, the bubble reads angles up to 90 degrees and indicates 0 degrees when you are level. It’s available online at the Apple App Store.
